FreeCAD is an open-source, free 3D modeling software built on OpenCASCADE technology. OpenCASCADE is an open-source core for CAD/CAM/CAE geometric modeling developed by Matra Datavision in France, serving as the development platform for the renowned CAD software EUCLID. FreeCAD is designed to be particularly useful in mechanical engineering and product design but is also applicable to a broader range of engineering applications, such as architecture and other engineering disciplines.

Open Source and Free: FreeCAD is open-source, meaning its source code is publicly available for anyone to view, modify, and use. This not only fosters the ongoing development of the software but also allows users to customize it according to their needs. Additionally, as a free software, it reduces the cost of use, making it accessible to a wider audience.
Functional and Parametric Modeling: Based on the CAD/CAM/CAE geometric model core, FreeCAD offers functional and parametric modeling tools. This modeling approach allows for easy changes during the design process and recalculates based on the properties of other objects, significantly enhancing design flexibility and efficiency.

Software Features

Cross-Platform Support: FreeCAD supports Windows, Mac, and Linux systems, allowing users to seamlessly switch between different operating systems without worrying about compatibility issues.
Rich API and Scripting Support: FreeCAD provides a rich Python API that enables users to extend the software's functionality through programming. Moreover, it includes a Python script interpreter that covers almost all of FreeCAD's applications, interfaces, geometry, and 3D view APIs, allowing entire modules to be programmed in Python, further enhancing its customization and flexibility.
Broad Application Areas: FreeCAD is not only suitable for mechanical engineering and product design but also extends its reach to broader engineering applications, such as architecture and other engineering fields. This versatility makes it capable of meeting the needs of users across various industries and has a wide application prospect.


Powerful Geometry Kernel and Tools: FreeCAD, leveraging Open CASCADE technology, boasts a robust geometry kernel and a wealth of tools for creating and modifying objects, including complex boolean operations, fillets, shape clean-up, and more. This enables users to effortlessly perform various intricate geometric operations and designs.
